An apparatus for and method of performing orthogonal light sheet microscopy (OLM) and computer optical tomography (COT) simultaneously in a single device are provided. The dual-mode imaging microscope allows for the use of both OLM and COT in a single instrument. This dual-mode device will allow researchers to have access to both types of microscopy, allowing access to the widest possible selection of samples, and improved imaging results. In addition, the device will reduce the high costs and space requirements associated with owning two different imagers (OLM and COT).

Simultaneous orthogonal light sheet microscopy and computed optical tomography

An apparatus for and method of performing light sheet microscopy (LISH) and light scanning microscopy (RAPS) in a single device are provided. The dual-mode imaging microscope allows for the use of both LISH and RAPS in a single instrument. This dual-mode device will allow researchers to have access to both types of microscopy, allowing access to the widest possible selection of samples. In addition, the device will reduce the high costs and space requirements associated with owning two different microscopes (LISH and RAPS).

Dual-mode raster point scanning/light sheet illumination microscope

An apparatus for and method of performing multi-photon light sheet microscopy (MP-LISH), combining multi-photon excited fluorescence with the orthogonal illumination of light sheet microscopy are provided. With live imaging of wholeand zebrafish embryos, the high performance of MP-LISH compared to current state-of-the-art imaging techniques in maintaining good signal and high spatial resolution deep inside biological tissues (two times deeper than one-photon light sheet microscopy), in acquisition speed (more than one order of magnitude faster than conventional two-photon laser scanning microscopy), and in low phototoxicity are demonstrated. The inherent multi-modality of this new imaging technique is also demonstrated second harmonic generation light sheet microscopy to detect collagen in mouse tail tissue. Together, these properties create the potential for a wide range of applications for MP-LISH in 4D imaging of live biological systems.
